Test the Android app on the local emulator, leaving the emulator running when you finish.
Build and install only when needed, capture focused diagnostics, and report results in terms of emulator status, build, install, tests, logcat evidence, diagnosis, and artifacts.
Prioritize upload automation failures, WebView behavior, and actionable root-cause evidence over broad exploratory testing.
